We're still in the design/layout phase of our new sanctuary. I'm not jumping the gun because we're breaking ground in about one month, the whole sanctuary is on a concrete slab, all wiring and A/C will be in conduits in the concrete. The concrete will be poured by Thanksgiving!
Now that I've seen it, I think I like that idea of a movable sub. I'll have them frame the original spots, run the wire to those locations, then close it up and put a speaker connector on the wall. That way I can try all sorts of options and still keep the option open of putting them in the wall.
Do I need the frog, lunch timer, and coffee thermos?
